The last one: A new species of Osteocephalus (Anura: Hylidae) from Colombia, with comments on the morphological and behavioral diversity within the genus

Abstract

A new species of Osteocephalus (Anura: Hylidae) from Colombia, with comments on the morphological and behavioral diversity within the genus. A striking, undescribed species of Osteocephalus from the Amazonian slopes of the Andes in Departamento de Putumayo in southern Colombia is a member of the Osteocephalus buckleyi Group. Aside from minor morphological characters, the new species differs from all other members of the group by having a golden yellow iris with a median horizontal black stripe. The diversity in morphological and reproductive behavior reveals various features that are phylogenetically signifcant, but several species remain to be described.
